  Changes between 1.0.1j and 1.0.2 [xx XXX xxxx]
 
+   *) Tighten handling of the ChangeCipherSpec (CCS) message: reject
+      early CCS messages during renegotiation. (Note that because
+      renegotiation is encrypted, this early CCS was not exploitable.)
+      [Emilia Käsper]
+
+   *) Tighten client-side session ticket handling during renegotiation:
+      ensure that the client only accepts a session ticket if the server sends
+      the extension anew in the ServerHello. Previously, a TLS client would
+      reuse the old extension state and thus accept a session ticket if one was
+      announced in the initial ServerHello.
+
+      Similarly, ensure that the client requires a session ticket if one
+      was advertised in the ServerHello. Previously, a TLS client would
+      ignore a missing NewSessionTicket message.

   *) Accelerated NIST P-256 elliptic curve implementation for x86_64
      (other platforms pending).
